Umatshini wonke yeyona yunithi isisisekoivalveindibano, kunye namalungu amaninzi enza iinxalenye zevalvu (njengebhonethi yevalvu, idiski yevalvu, njl. njl.). Inkqubo yokuhlanganisa yamacandelo amaninzi ibizwa ngokuba yindibano yecandelo, kwaye inkqubo yokuhlanganisa yamacandelo amaninzi kunye namacandelo ibizwa ngokuba yindibano epheleleyo. Umsebenzi weNdibano unempembelelo enkulu kumgangatho wemveliso. Nangona uyilo luchanekile kwaye iindawo zifanelekile, ukuba indibano ayifanelekanga, i-valve ayiyi kuhlangabezana neemfuno zemimiselo, kwaye ikhokelela ekuvuzeni kwetywina.
Kukho iindlela ezintathu eziqhelekileyo zokudibanisa ivalve, ezizezi, indlela yokutshintshana okupheleleyo, indlela yokutshintshana okulinganiselweyo, indlela yokulungisa.
Gqibezela indlela yokutshintshana
Xa i-valve ihlanganiswe ngendlela epheleleyo yokutshintshana, inxalenye nganye yevalve inokuhlanganiswa ngaphandle kokulungiswa kunye nokukhethwa, kwaye imveliso inokuhlangabezana neemfuno zobugcisa ezichaziweyo emva kokuhlanganisana. Ngeli xesha, iinxalenye ze-valve kufuneka zicutshungulwe ngokupheleleyo ngokuhambelana neemfuno zokuyila ukuhlangabezana neemfuno zokuchaneka komgangatho kunye nokunyamezela kwejometri. Iingenelo zendlela yokutshintshiselana epheleleyo yile: umsebenzi wendibano ulula kwaye unoqoqosho, umsebenzi awufuni iqondo eliphezulu lobuchule, ukuveliswa kwenkqubo yendibano kuphezulu, kwaye kulula ukuququzelela umgca wendibano kunye nemveliso yobuchwephesha. . Nangona kunjalo, xa sithetha ngokupheleleyo, xa indibano epheleleyo yokutshintshwa yamkelwa, ukuchaneka komatshini kufuneka kube phezulu. Ilungele ivalve yeglowubhu, ivalve yokukhangela, ivalve yebhola kunye nezinye iivalve ezinesakhiwo esilula kunye nedayamitha encinci naphakathi.
Indlela yokutshintshiselana encinci
I-valve ihlanganiswe yindlela yokutshintshana okulinganiselweyo, kwaye umatshini wonke unokucutshungulwa ngokuchaneka kwezoqoqosho. Xa kuhlanganiswa, ubungakanani obuthile obunohlengahlengiso kunye nomphumo wembuyekezo bunokukhethwa ukufezekisa ukuchaneka kwendibano echaziweyo. Umgaqo wendlela yokukhetha iyafana nendlela yokulungisa, kodwa indlela yokutshintsha ubungakanani bendandatho yembuyekezo iyahluka. Owokuqala kukutshintsha ubungakanani beringi yembuyekezo ngokukhetha izincedisi, ngelixa lo mva kukutshintsha ubungakanani beringi yembuyekezo ngokulungisa izincedisi. Umzekelo: umbindi ophezulu kunye nohlengahlengiso lwe-gasket yohlobo lwevalve yokulawula uhlobo lwevalve ye-ram ye-wedge yesango, i-gasket yokulungelelanisa phakathi kwemizimba emibini yevalve yebhola eyahlulayo, njl. ukuchaneka kwendibano, kwaye ufezekise ukuchaneka kwendibano efunekayo ngokulungelelanisa ubukhulu be-gasket. Ukuze kuqinisekiswe ukuba iindawo zembuyekezo ezisisigxina zinokukhethwa kwiimeko ezahlukeneyo, kuyimfuneko ukwenza iseti yewasha kunye neenxalenye zembuyekezo ye-shaft sleeve kunye nobukhulu obahlukeneyo kunye nobukhulu kwangaphambili kukhetho lwemodeli yevalve yolawulo lwehydraulic ngexesha lokuhlanganisa.
Indlela yokulungisa
I-valve ihlanganiswe ngendlela yokulungisa, iinxalenye zinokuthi zicutshungulwe ngokuchaneka kwezoqoqosho, kwaye ngoko ubungakanani obuthile ngohlengahlengiso kunye nomphumo wembuyekezo unokulungiswa ngexesha lokuhlanganisana, ukuze kufezekiswe injongo yendibano echaziweyo. Ngokomzekelo, isango kunye ne-valve ye-valve ye-valve ye-wedge gate, ngenxa yeendleko eziphezulu zokufezekisa iimfuno zokutshintshiselana, abaninzi abavelisi bamkela inkqubo yokulungisa. Oko kukuthi, ekusileni kokugqibela kwendawo yokutywinwa kwesango ukulawula ubungakanani bokuvula, ipleyiti kufuneka ihambelane nobukhulu bokuvulwa kwendawo yokutywinwa komzimba wevalve, ukuze kufezekiswe iimfuno zokutywinwa kokugqibela. Le ndlela yokwandisa inkqubo yokumatanisa ipleyiti, kodwa ilula kakhulu iimfuno zokuchaneka kobukhulu benkqubo yangaphambili yokucwangcisa. Ukusebenza kwezakhono zenkqubo yokudibanisa ipleyiti ngabasebenzi abakhethekileyo akuyi kuchaphazela ukusebenza kakuhle kwemveliso kuyo yonke. Inkqubo yokuhlanganisa i-valve: iivalve zihlanganiswe ngabanye kwindawo esisigxina. Ukuhlanganiswa kweengxenye kunye namacandelo kunye nendibano jikelele yeevalvu zenziwa kwi-workshop yendibano, kwaye zonke iinxalenye eziyimfuneko kunye namacandelo zithunyelwa kwindawo yendibano. Ngokuqhelekileyo, mangaphi amaqela abasebenzi abajongene nendibano yamacandelo kunye neNdibano yeZizwe eziManyeneyo ngaxeshanye, engafinyeleli nje kuphela umjikelo wendibano, kodwa iququzelele ukusetyenziswa kwezixhobo zokuhlanganisana ezikhethekileyo, kwaye ineemfuno eziphantsi kumgangatho wobugcisa bomsebenzi. abasebenzi.
